Windows 8.1, BootCamp does not find the ISO image.

Question

Windows 8.1, BootCamp does not find the ISO image.

When I try to install Windows 8.1, BootCamp does not find the ISO image.

I purchased Windows 8.1 Pro, I downloaded the .exe requested file from a Windows computer, performed the steps recommended by Microsoft in order to create the ISO file saving it on a flash drive as well and, as a precaution, on a DVD too.
I performed the "Download the latest Windows Support Software from Apple" step directly into another flash drive and having it completed BootCamp displays the following message:
"The installer disc could not be found – Insert the Windows installer disc and wait a few seconds for the disc to be recognized. "
So happens that I have tried this using the DVD, pendrive and also copying the ISO file to the desktop and to the "Documents" folder as recommended in certain websites, but none of this has made the process go ahead. What can I do?

My equipment is a mid 2011 iMac running Mac OSX 10.10.1.

iMac, OS X Yosemite (10.10)

Hi Helton,

Could you please explain what exactly you did to make it work? I'm facing the same issue with ISO for installing Windows 8.1 in my MBP. Below is the link I referred.

Re: Boot Camp will not recognize iso image

However, it wasn't working the way it is explained. The ISO is still not recognized.

Would it work if we burn the content to a DVD using nero and using it in BootCamp?

If you have the ISO on your Desktop, can you double click on it and does it mount and show you files? It could be that the ISO is corrupted.

The ISO seems to be intact. In Bootcamp Assistant, if you check only the first two boxes, and a USB2.0 flash drive more than 4GB plugged in, when the box for choosing ISO comes up, drag the ISO image file from you Desktop to the box and click continue. Does that work?

Unfortunately it did not work.

This is the screen before I press the "Continue" button. I already have downloaded on the first option.

This is the warning that BootCamp does not find the ISO disk (in Portuguese language of Brazil):

You do not have an option to use an ISO image on Bootcamp Assistant, so your iMac 2011 must use a physical DVD Windows disk. You can burn the ISO to a DVD using

Disk Utility 12.x: Burn a disk image to a CD or DVD

From Boot Camp 5.1: Frequently asked questions - Apple Support

Can I install Windows from an ISO image?

To find out if your Mac supports that feature, open Boot Camp Assistant, then click the Continue button. If you see a checkbox labeled “Create a Windows 7 or later install disk,” your Mac can install Windows from an ISO image.

Loner T, your suggestion gave me a doubt:

I own the iso image already burned to a DVD from a Windows PC, according to what is stated by Microsoft. The content of it is exactly the same window shot that I sent earlier. I took the instructions here:

http://windows.microsoft.com/en-us/windows-8/create-reset-refresh-media

Although I have inserted in this DVD SuperDrive, the result was the same. It is not meant for installation to BootCamp?

Are you using the built-in iMac superdrive or an external Optical drive? If you insert the DVD in the built-in Optical drive (not an external Optical drive), can the DVD be read successfully?

Dear Loner T,

thanks to my coworker, the solution was unpacking from that ISO file which I had recorded (according to the steps indicated by Microsoft), but now using Nero software (Windows) and then recording by the most common way in a new DVD. See the screen of the first DVD before unpacking:

This true saga only demonstrated that the generated ISO file as an option at the time of the Windows installation, is not for direct installation through BootCamp, and as a I could check, even for direct installation on a Windows PC. See the last DVD burned using Nero and again recorded:

The execution of BootCamp, was perfect

Thank you for attention to my problem!

You are the one person I found on the entire internet who had the same problem I do. I have the exact same issues, I can't get the ISO image read, and I have it on a DVD. I am confused by your solution though. What exactly did you do? Thanks.

Is it unreadable on Mac, but readable on a Windows PC? Does it show up in Disk Utility?

You can take your DVD (with the ISO image) to a PC, and use Nero or Toast to open it. You can then burn it using Disk Utility.

On a PC, if you right click on the DVD and look at Properties, what is the format of the DVD?

I don't own a PC, I used a friend's to burn the DVD, so I don't have a PC that I can use right now. I probably will be able to tomorrow.

Which is the same issue as the OP. On the Mac, does your DVD show up in Disc Utility?
